The Jesmonite range of products, chameleon-like materials par excellence.
AC100 and AC730 are two Jesmonite products consisting of 2-component materials in water phase.
The big advantage? They are an environmentally friendly alternative to other resin systems, more durable and easier to use.
But then. How do you choose one or the other and what to consider?
AC100, infinite creativity
AC100 is water-based, solvent-free, risk-free and can reproduce almost any surface, colour or texture. There are no limits to your imagination here!
How to mix? Quite simple, we are at a ratio of 1 (liquid) to 2.5 (powder) by weight. You’ll have a texture that’s easy to mix and pour into all the little nooks and crannies and most importantly… you can create almost anything you want! Tints, marbled effect, terrazzo, glitter, …
This product is extremely easy to work with and above all, fast. (You will have an average of 10 minutes once your mixture is ready and once cast, depending on the size of your mould, you will be able to demould between 30 minutes and 2 hours. Pretty cool, huh?)
It can see water but not a lot of it. To protect your creations even better, you can use a sealer (note that this does not make it “water-proof” but “water-resistant”).
Nevertheless, if we compare it to plaster, it is clearly more resistant and lighter!
The finish or rendering will be “smooth” in nature.
Ideal for indoor use!
AC730, a real stone effect
AC730 is more of a cement base. It is a mixture of water-based acrylic and a cement-based powder.
This is a heavy, robust product that will allow you to make pieces identical to what you could do with concrete, but still with the desire for simplicity and greater lightness!
Ratios ? We are moving to a ratio of 5 powders to 1 liquid.
(By the way, don’t worry if the mixture seems too sandy at first. Patience…. As you go along, you’ll get a smoother, more consistent mixture. (However, much thicker than with the AC100)
The working time will be longer, and the drying time as well (Wait 4 hours before unmoulding if it is a casting)
3 major differences compared to AC100: Pigments already integrated, a real “rough stone” aspect and the possibility of using it outdoors! (It should be noted that this material can also be used in layering for façade cladding)
To obtain this beautiful “concrete – authentic rough stone” look that we love, you will have to treat the surfaces afterwards with acid (or …. with white vinegar, which also works very well). Don’t panic, once again, it’s within everyone’s reach. This is really when you will see the real thing and all its splendour! (The biggest difference will be seen with Grey Granite where your black speckled glitter effect will magically appear)
What about you? Are you more of the AC100 or AC730 team?
